Sky Eye Chopper 13 gives us a bird’s eye view. At 9 a.m. Monday, Department of Transportation crews will close N. Howard Street in both directions–between North and Mount Royal Avenues.

A few weeks ago, there was a water main break. So crews will replace an 80-year-old valve.

“Because of the level of the trenching that has to happen, they need to close Howard Street to all traffic. And that carries about 30,000 cars a day,” said Frank Murphy, Deputy Director, Md. Department of Transportation.

The repairs will take three to four weeks, so expect significant delays.

“North Avenue will lose one of its two eastbound through lanes at that intersection. So it will experience congestion,” Murphy said. “And because Martin Luther King Boulevard is the main feeder to Howard Street, anybody getting to and from Martin Luther King Boulevard will have to find other ways to go.”

Detour signs will be posted. Drivers should map out other routes.

Over the next five years, Baltimore will replace 150 miles of water mains at a cost of $300 million.
